The `client_id` in the response is used for OAuth 2.0 client credentials authentication. This endpoint is idempotent by `external_id`: a second POST with the same `external_id` returns the existing record. ## OpenAPI ````yaml en/API/Management-API.yaml POST /service-accounts openapi: 3.1.0 info: title: CData Connect AI Management API version: v1 description: > The Connect AI Management API provides programmatic control over enterprise platform administration. Base path: /api/v1/admin. Use it to manage users, service accounts, roles, and resource permissions without manual UI operations. The API follows OAS 3.0 standards with OAuth 2.0 scoped authentication. On versioning: the version prefix is incremented when breaking changes require it. A new /api/v2/admin path will be introduced with a 6-month deprecation notice before any v1 endpoint is retired. On human users vs. service accounts: human users are provisioned and lifecycle-managed by SCIM; the Management API handles direct overrides and atomic deprovisioning. Service accounts (CI/CD pipelines, IaC tooling, Terraform) are fully managed via the Management API and are not SCIM-owned. servers: - url: https://cloud.cdata.com/api/v1/admin description: Production base URL security: - oauth2: [] tags: - name: Users description: > Lifecycle management for human users: create, update, deprovision, and manage direct role assignments, workspace-scoped roles, and direct resource permissions.
